Yes, the issue is the one piece of JavaScript depending on another.
Given JavaScript's dynamic nature we didn't want to compile in
explicit dependencies into the generated class files.
The shell is not strictly required; if you create a scope and then
load the generated classes as org.mozilla.javascript.Script instances
and then call their exec() methods in turn on the same scope you
should get the behavior you desire.
